Walks on the Wild Side

There are people who love zoos, and there are people who hate them. Apparently, the same goes for animals. After a 3-year review of studies of animal behavior at 40 zoos, two researchers from England have concluded that animals needing lots of space in the wild often do horribly in zoos. Their babies tend to die at higher rates. And they are more likely to pace back and forth, a behavior that signals boredom or distress. The researchers looked at 35 meat-eating animals, including lions, cheetahs, brown and black bears, mink, brown hyenas, and arctic foxes. Results showed that animals that cover the most ground when they're allowed to roam free are the ones that suffer the most in zoos. Polar bears, for example, often develop severe pacing habits in captivity, possibly because they feel so cramped. In the wild, polar bears range over at least 1,200 square kilometers every year. In zoos, they get about a millionth as much space. Arctic foxes, on the other hand, usually cover less than a square kilometer in the wild, and they seem to deal with zoo life just fine. Researchers aren't quite sure what to make of the somewhat controversial findings. Animals that have large home ranges are often among the most threatened species. Now, it could be even harder to protect them in captivity. Zoos might have to come up with better exhibit designs that give animals enough space to feel like they're at home.E. Sohn
